Abstract: Percussion device, includes a housing and two movable bodies, an impact body for an impact pin protruding from the housing, and a balancing body for counterbalancing impact motions of the impact body. The housing includes springs, which constantly strive to bring the bodies towards each other and against the action of which the bodies may be separated axially. The balancing body is rotatable, via a drive spindle connected to a driving source the spindle being mounted in a bearing member, at least one of the bodies including an oblique surface, which, by contact against the other body, transforms the rotary motion of the balancing body into axial motions of the impact body. Rotation of the bearing member is prevented by a helical pressure spring attached to the bearing member and the housing. In this way, tangential vibrations cannot be transferred from the drive spindle to the housing.
